In geographic range options, which selection should be made for radio-based assessments?

• A. Radio
• B. VHF
• C. Satellite
• D. Visual

Answer: (A)

When an assessment is described as radio-based, the method used to determine geographic range relies on radio transmissions. Radio is the broad category that encompasses all radio communications, so it directly matches the described approach. A specific frequency band like VHF is still radio, but the question points to the general radio-based method rather than a particular band. Satellite implies a different, satellite-led approach, and Visual uses sight rather than signals, so they don’t align with a radio-based assessment. Therefore, selecting the radio option best fits the described method.
